Analysis

The pilot reported that, while making a video of a boat, he flew the helicopter with the doors removed about 20 ft above the water and 3/4 mile offshore and saw seabirds ahead crossing right to left but he thought they would be not be a problem. Shortly after seeing the birds, he initiated a right turn to follow the boat, and while he was looking over his right shoulder, he felt an object, which he believed was a seabird, strike him in the back of the head. While dazed from the head strike, he flared to reduce speed, and the helicopter settled into the water. He then applied left lateral cyclic to stop the main rotor blade's rotation, and the helicopter rolled left and inverted in the water. The helicopter sustained substantial damage to the fuselage and main rotor blades. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
